of-clarnpi'ng all the cutters in position upon 28 upon the upper cutter arbor.

' Between each pair of the cutters, s 'acing collars 15 are placed for the purpose o sepaone from the other the 1616 areclamped collars and 17 l-Tare nuts threaded to the arbors for the purpose the arbor 6.

18 18 are strippers adapted to clear the metal from the cutters.

Motion is communicated to the cutters for means of pinions 20, gear 21, shaft 22, pinion 23 on shaft 22 meshing with a gear 24 upon the lower cutter arbor, and by pinion 25 on said shaft 22 meshing with pinion 26 on shaft 27, the pinion 26 meshing in turn with gear.

. It will be understood that the invention ma be used for trimming the edges of single strips and slitting them at the same time instead of cutting the whole sheet 14 atonce into strips 13 and simultaneously slitting the strips.

l clain1: 1. In cutting rolls' for sheet metal, the

their edges continuous on one side and interrupted on the other, of slitting interrupted edges arrange between the shearing cutters, a roll upon which all of said cutters are mounted, an opposing roll, similar shearing cutters on said opposing rolls countering the first mentioned shearing cuttors, and similar slitting'cutters also on the opposing roll between the shear' cutters and countering thefirst mentione slitting cutters. p

2. The combination in a. machinelfor cutting sheet metal, of opposing arborsor man-- rovided with shearing fcutters drels, each on one s de and having continuous edges interrupted edges on the other side, fandeach also provided withslitting cuttersghavlng interrupted cutting edges, all the cutters of one arbor countering like cuttersj uppn the 1 other arbor.

3. The combination 111 a machine for cutting sheet metal, of opposi arborsfor inandrels, each provided with a p uralit of shearing cutters spaced apart, and a .p slitting cutters located-between and the spaces between the shearing cutters, all

the cutters of one arbor countering like out t'ers upon the other arbor.

4. The machine for manufacturing gpended metal from wide sheets consisting bf opposing rolls each armed with shearing cuttei's for dividing the sheet into narrow sheets or strips, and with slitting cutters for slitting the several narrow sheets preparatory to expanding them, the cutters upon each rollcountering like cutters upon the-other roll.
